Prop. Window.: 10ºF
Time Period..: 30 s
The Modulating Cooling Proportional Window is the control range of
the Modulating Signal above and below the Active Supply Air Setpoint.
The larger the Modulating Cooling Proportional Window, the smaller
the signal adjustment per Time Period will be for each ºF the supply air
is from the Active Supply Air Temperature Setpoint. The Time Period
is the delay before another signal increase or decrease can be made
and is user-adjustable. Short Time Periods may cause hunting of the
Modulating Signal. Defaults are 10ºF and 30 seconds.

For the Controller to properly calculate the outside air CFM you need
to enter the inside area (sq. ft.) of the outdoor air duct/damper. When
measuring the outdoor air damper area, be sure to measure the inside
dimensions of the damper. The more accurate the measurements, the
more accurate the CFM reading will be. This value needs to be accurate
to 2 decimal places. Default is 0.00.
